Actually not quite, see comments.

So you're saying Outputter is broken?

I think you're assuming that this high byte begins life as
part of an XML file (you talk about entities being expanded by
the parser, etc)  And that it's decoded from that source
into a single byte.

It doesn't come from an initial external XML file.

It gets into the tree in-memory with an addContent(String)

Then you say "On output you no longer have any character
entity so the char is output as is."  That last phrase,
"is output as is" is the crux of the problem.  And are you
saying that's propper behavior or a bug?

A message to the list:

Folks, I'm sorry for all the traffic this has generated on
the list, but as you see it seems like we're getting different
answers.  And no answer (aside from overriding the Outputter)
seems to mesh with the observed behavior.

I do think that the Outputter is broken, even in it's default UTF-8 mode.
(Sorry but I'm not quite brave enough to take a whack at fixing it.)
